Biographical / Historical

The Cooper Union campus has fluctuated in size over the decades, but its nucleus has always been the Foundation Building, which features in most of the images in this collection. While the exterior of the Foundation Building has remained fundamentally unchanged since it was built in the 1850s, the neighborhood around it has fluctuated as much if not more than the Cooper campus, and these changes are revealed in postcards and sterescopes: variations in the size and shape of Cooper Square and Astor Place; in the heights and signage of buildings; in the vehicles and pedestrians on the street; and, most strikingly, in the presence or absence of the Third Avenue Elevated that ran down from 1878 until its deconstruction in 1955.
